SPRING STRUCTURE.

Specification of Letters Patent.

PatentedrMay 14, 1907.

Application filed October 1,1906. Serial No. 336,879.

1'0 (tZZ w/mnt zit may concern.-

.Be it' known that I, Anrncn STEDMA'N, a citizen of the United States of America, and a resident of Cincinnati, in the county of Harm-- Ohio, have invented cerin Spring tain new and useful Improvements a specifi- Structures, of which the following is cation.

lVIy invention relates to improvements in spring-structures, more especially to such structures as comprise oneor more helical or coil springs having intersecting tie-wires,,the

ing a number of said coil springs and supporting them in an upright operative position for use in such: articles of manufacture as beds, couches and seats, or the like.

My invention consists in an' article of manufacture comprising one or more coil springs and tie devices, the latter uniting ahd supporting the position and such tie devices being electrically-welded at their several intersections with said coil springs and adapted to form a spring structure foruse in beds, couches and seats.

The accompanying drawing illustrates a diagraphic plan viewof one. of the many forms of spring-structure to which my invention herein is adapted.

In said view, 1 indicates each one 'of a number of coil-springs arranged. in parallel rows or series at suitable distances apart for use in such structures as 2 represents each one o af series oi longitudinal tie-wires, and 3 series of transverse tie-Wires, arranged as customary in connection with said coils 1, the respective Wires. 2 intersecting the respective Wires 3 at points i concentric to each of said springs 1. j

At the various intersections or crossingpoints 5 of each of the tie-wires 2 and 3 with more rigidv at its former in an upright operative! beds, couches and seats, as-

indicates each one of a each oi the coils 1 an electrically-welded joint is made or effected in any suita lo manner, so that said. tic-Wires are rigidly and firmly bound or connected to said springs without the use ofother means. The said tie-wires may be bent or not, as desired, at said intersections with the coils, and the intersections of the tie-wires with each other may" or may not be electrical1ywelded, as desired, at the respective, points concentric to the several springs in order to make the structure the joints and of greater stability for use: It is obvious that structure than the one shown and above de scribed can be electrically-welded at intersecting points: between the tie devices and the springs and I 'do not wish to be under stood as limiting myself to the precise form shown.

I claim 1 A spring-structure comprising one 'or more coils and one or more tie-wires .or the like intersecting saidcoils, the intersections between said coils and ties being electricallywelded together.

2. A spring-structure comprising one or more series or rows of coil-springs and intersecting tie wires, suchtie-wires intersecting together.

3. A spring-structure comprising-one or more coils and one or more tie-wires, the latter intersecting the outer ends of said coils and intersecting each other concentric to said coils, and electrically-welded joints at each of said intersections.
